To all whom it may concern.'

Be it known that. I, SAMUELC. REALE, a citizen of -vthmU-nited States, residing at Los Angeles, in the county Oi Los Angeles and State of California, have invented new and useful Impro vemenfs in Automatic' Feed and Delivery Mechanism for Printing-Presses, of which the following is a specification.

, My invention relates to an automatic feed and delivery mechanism for a printing press, in which the paper is automatically fed to a rotary cylinder to bevprinted and the sheet will then be automatically delivered ont of the machine. Heretofore in printing presses with traveling paper carrying mechanism, the movement has been effected by means of racks apd gears, and in Starting the carrying mechanism in either direction there was always a jar and shock, which soon wears out the gears, racks the machine and renders high speed impracticable. With my improved machine ,these defects are avoided as the p aper carrier is brought to rest and started from restquietly and gradually, there.- by rendering it susceptible of very high speed with infinitesimal wear.

The object of my invention is to providean ellicicnt, automatic and rapid acting feed and delivery mechanism or a printing press. 1 accomplish this object by the mechanism described herein and illustrated in the accompanying drawings, in whicliz v Figure l-is a side elevation of a printing press, partly in section, with my improved automatic feed and delivery mechanism. Fig. 2-is a sectional plan of same on line 2-2 of Fig. 1. Fig. 3-is an enlarged' fragmental view, partlyin section, of the paper feed mechanism. Fig. 4-is`aperspective view of the cylinder and delivery apron. Fig. 5-is a sectional view of the cylinder, the type carrying frame and delivery apron in the act of delivering a printed sheet ott the cylinder to the collection box. Fig. (iz-is a frag- .mentary sectional view oi the paper'carrier feed and the adjustable back. Fig. 7 :4 is a rear view of the paper carrier, showing the reciprocating mechanism. Fig. 8 is a sectional detail of air connections.

In one side of the frame 10 of the machine is mounted the driving shait 11, on the outer end of which is the power pulley 12, driven in anysuitable manner. Shaft l11 has rigidly mounted thereona pinion 13 which meshes with gear 14. Gear 14'isn1ou11ted on crank shaft 15 which is provided with a crank 16; the arms of said crank project on both sides of shaft 15, as shown in Fig. 2, and the unconnected ends are provided with An arm has a cam slot 21 therein` the end oi which projects downwardly as shown in Fig. 1. Within this slot is a roller 22, which is mounted upon boli 23, whi'ch holt is the pivot. that unites pitman 17 and arm 18.` The arm 2O has allever 24'pivoted at 25 to a b earing 26, secured to the frame of the machine at the'center of the rear end thereof. An adjustable pitman 27 is secured. by bolt 28 to lever 24, said bolt passing through a. slot 24 in the lever to adjust the-travel of paper carrior 29. A rod 30 is secured to the sides of the carrier 29 and the forward -end f the pitman 27 is mounted thereon. v

The sides of the paper carrier 29 are slidably mounted in ways 31A of the supporting frame 32 a'nd reciprocates therein, which frame is rigidly secured to the iop of said frames 10. The bottom of the paper carrier is composed of fingers 33 which are slidably mounted in ways 34 in the bottom of frame 32, upon which the 1ingcrs reciprocate; these fingers are rigidly fastened t-o a back plate. 35 of the paper carrier and are adjustable to paper of different widths. This back plate. is transversely mounted to an adjustable slide 3G, which slide is secured to a ledge of the sides of the paper carrier 29 by means of wing nut 37. A guide plate 38 is adjustably mounted to the hack plate- 35 by means of wing bolt 38, projecting through slot 39, and prevents lateral displacement of the paper. A like guide plate is at the other side of the carrier. The front plate 40 of the paper carrier 4is hinged at 41 to an adjustable afm 42, which is secured to alledge on the sides of the carrier 29. A bolt 42 passes through the front plate 40 and screws intothe side of the carrier; a spring 43 on the bolt holds the front plate, yieldingly in a vert-ical position against the front of* ie paper carrier 29. It will be observed that the loweiiend of the front plate 40 is engaged by the casing of air chamber 5] of the cylinder 44, which as said cylinder rotates will cause the lower portion of the plate to swing outwardly until it passes below the end of the plate, when the same will spring .back-against the front end of the carrier, 'l hereby packing the paper.

At each end of cylinder 44 are cog gears 45 which mesh with inclined racks 46, situated at the Sides of the -type carrying frame 19, whereby as said frame is moved on its guideways, said cylinder is caused to rotate in n reverse. direction to which the type carrying frame 19 is traveling, by means of pinion 47 which meshes with an inclined rack 4S, rigidly secured to the outer sides of the' frame 10. Pinion 47 is keyed to shalt 49 which 'rotates in a slide block 5(1'in guidon-'ay 10 of the mn.-

chine frame, and said shaft is keyed lo the c og gears and the cylinder 44. A similar pinion and cog gear is provided at the lother end of the shaft. Within cylinder 44 is an air chamber 51 which is provided with a plurality o ports 52, which open through the top o casing of the`chamber, which easing forms a portion 0i the cylinder, the same being cutaway at this point. A pipe 53 connects chamber 51 with a bored portion 49- of shaft 49, upon which the cylinderis mounted. This bored portion oft-he shaft passes through cog gear 45, the slide block 50 in the guideway 10 and through the pinion 47 and an air chamber 54. Within air chamber 54 the shaft is perforated by'perforations 49|. The air chamber is connected to the air controlling valve 55; a portion 56 of thisconnection is flexible. A pipe 58 connects valve 55 tothe air pump cylinder 59. A

spripg pressed stem 60 works in valve 55 and on its outer end is a 'bearing wheel G1, -which has a rolling contact with' cam 62, which cam is mounted upon shaft 15. Pivotally connected with cam G2 is a pitman 63, the other en d of said pitman is connected to a piston which has a working fit in air pump cylinder 59. The details of the suction mechanism are fully illustrated and described in the application of H. E. Brett, filed Ian. 4-(17, No. 350,833, whose invention they are and for that reason is not more fully described herein.

Secured to shaft 644is the delivery apron 65, (see Fig. 4) which apron is provided with projecting'ingers 65 y that pass into grooves 66, situated on the top of the air chamber 51 of the cylinder 44.` Curved arrhs 67 are secured to the deliver)r apron at each end and project i downwardly therefrom', andsaid arms ride upon cams 68 and are held spring pressed against the same by spring 64TL secured to the shaft 64 and to its bearings and when the arms reach the cutaway portion of the cams,

the lingers 65 drop down into the grooves 66 and are .raised up out of the grooves when the circular portion of. thecam reached. The `delivery-apron is provided with an upwardly exten I ing arm 69, (see Fig. 3)

1 .which engages a lug 70 on the side ofthe -frame 10.

.When the air chamber 5l is bleingexhausted; the lug 70'preven'ts`thearms of the deliveryapron from comirigin contact with 4the cutawayportion of the cam 68,

thereby keeping them from engaging the paper on the cylinder. The shaft 64 of the delivery apron is mounted to the side plates 50,1whi.ch plates are integral with the slide block 50 and consequently said shaft moves with the cylinder 44.

A plurality of 4fingers 71 aresecured to bar72, by

' means of set screwseo that they can be adjusted.v Bar 72 is moved by the L-sh`aped lever 73, at the outer end of which is a. roller 74, which roller engages and'ridcs upon track-H74L and is held in contact by spring 73 with said track- This track is'secured to the paper carrier. A Y l Friction. rollers 75 are. mounted on shaft 76.' This shaft rotates in a spring pressed bearing 77, which keep said rollers in contact with the paper 78 on cylinder 44, as it is released from the suction 'ports 52 of the air vchamber 51 mounted in the cylinder.

A collection box 79 is mounted atthe lowest ends of the carrying frame 19, said box having an inclined floor 79which terminates at a transverse aperture 79" in the llower end ofthe box. .1

f lhe type form box 84 rests upon and is supported -by shafts` 85, l(only one is shown) which are flattened as shown in Fig. 5. v'These shafts are mounted in bearings secured to the bottom of the pocket of the frame 19. Levers 86 (only one is shown) oscillatc shafts 85 at a 'prcdvlrrnirlcd time, by mechanism not shown, lifting the form box Se and the printing typ'c 'to the paper 78 on the cylinder44 as it rotates over the form box and printing said paper. Said mechanism being 'fully described and illustrated in the application of said Brett.

The inlc font is secured to the type carrying frame 19 and has roller 8l therein, .which engagesthe inkingrollers 82, mounted in theI rear of side plates 50, which said plates are integral with slide block 50 which is mounted on shaft 49; Spreading rollers 83;

paper carrier is not moving and that it moves only while the roller 22 is traveling in the downwardly in' A c'linedportion of slot 21,and that the motion is gradually and gently imparted to thecar'rer as it is made when the pitman has its least motion, thereby avoiding any lshock or jar on the machine. Meanwhile the cam 62 on shaft 15 is so timed that just before the extreme limit of the forward movement of the paper c arrier has been reached, the lower sheet of paper inthe carrier is brought into-contact-with and rests upon ports 52 of the casing of air chamber51, at which time said chamber is thrown/co suction'byA meaus'of pump 59.. The racks 46 on the carrying frame 19 rotate the 'cylinder with paper upon it, and the stationary racks 48 mesl1-A ing the pinion 47 on said cylinder shaft 49, c ause the cylinder to travel in a reverse direction to that of the 'carrying frame, and as the cylinder rotates it moves 74 to support the front end of the paper, except theA bottom one, while thel cylinder 44 is withdrawing the underslieet. The cy1ixider,44 with a sheet of paper encircling it and held by theexhaust, proceeds down the inclined racks 46 and 48. has turnedshafts 85, lifting the'form box 84 and the type matter in contact with the sheet on the cylinder, printing said sheet as it rotates. The cylinder 44 still Meanwhile the lever 86 further rotates down the racks until the friction roller 75 comes in Contact with the end of the sheet held at the air chamber ports 52, when the printed sheet released from suction by the action of roller (51 of the air controlling valve 55, reaching the low side of the cam 62, releasing the suction in air chamber 5l.
